【OGG】OGG的单向复制配置-支持DDL(二)_OGG

一.2 前言部分

一.2.1 导读

各位技术爱好者，看完本文后，你可以掌握如下的技能，也可以学到一些其它你所不知道的知识，~O(∩_∩)O~：

① OGG的单向DDL实时复制功能

注意：本篇BLOG中代码部分需要特别关注的地方我都用黄色背景和红色字体来表示，比如下边的例子中，thread 1的最大归档日志号为33，thread 2的最大归档日志号为43是需要特别关注的地方。

一.2.4 本文简介

本文基于OGG的DML复制功能，加上DDL复制功能，后续会推出系列的OGG配置，包括双向复制，还有rac到单实例的复制等等，主要参考网址为：http://ylw6006.blog.51cto.com/all/470441/16 ，非常感谢斩月大师。

一.3 实验部分

一.3.1 实验目标

配置2台服务器，搭建OGG,实现hr用户下的数据ddl和DML复制功能。

【OGG】OGG的单向复制配置-支持DDL(二)_OGG_02

一.3.2 先验证之前的配置不支持DDL复制

验证之前的配置不支持DDL复制，这里在source端，新建一张表，发现无法复制到target端！target端也新建相同的表后，DML操作可以成功复制。

[oracle@orcltest ~]$ sqlplus hr/hr@ogg1

SQL*Plus: Release 11.2.0.3.0 Production on Wed Jun 10 16:18:03 2015

Connected to:

Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production

With the Partitioning, OLAP, Data Mining and Real Application Testing options

SQL> create table t2 (id number primary key,name varchar2(20));

Table created.

SQL> conn hr/hr@ogg2

Connected.

SQL> select tname from tab where tname='T2';

no rows selected

SQL> create table t2 (id number primary key,name varchar2(20));

Table created.

SQL> conn hr/hr@ogg1

Connected.

SQL> insert into t2 values (1,'one');

1 row created.

SQL> commit;

Commit complete.

SQL> conn hr/hr@ogg2

Connected.

SQL> select * from t2;

---------- --------------------

1 one

SQL>

此时source库：

GGSCI (orcltest) 26> dblogin userid ggusr@ogg1,password lhr

Successfully logged into database.

GGSCI (orcltest) 29> info trandata hr.t2

Logging of supplemental redo log data is disabled for table HR.T2.

GGSCI (orcltest) 30>

一.3.3 开始配置OGG支持DDL复制(在source端操作)

一.3.3.1 赋予ggusr用户相应的权限，修改全局配置文件添加ggschema参数

[oracle@orcltest ~]$ sqlplus sys/lhr@ogg1 as sysdba

SQL*Plus: Release 11.2.0.3.0 Production on Wed Jun 10 16:27:05 2015

With the Partitioning, OLAP, Data Mining and Real Application Testing options

SQL> grant execute on utl_file to ggusr;

Grant succeeded.

SQL>

[oracle@orcltest gg11]$ ggsci

一.3.3.2 运行相关的sql脚本

如果想使用DDL功能，需要在之前运行支持DDL的相关脚本。

1.@marker_setup.sql

2.@ddl_setup.sql

3.@role_setup.sql

4.GRANT GGS_GGSUSER_ROLE TO gguser

5.@ddl_enable.sql

6.@?/rdbms/admin/dbmspool.sql

7.@ddl_pin.sql ggusr
